ATTACHMENT FOR CULTIVATORS.

SPECIFICATION forming part of Letters Patent No. 692,729, dated February 4,1902.

' Application filed November 4, 1901. Serial No. 81,146 (No model.)

To all. whom it may concern.-

Be it known that I, JOSEPH STINE, a citizen of the United States, residing at Saybrook, in the county of McLean and State of Illinois, have invented a new and useful Attachment for Cultivators, of which the following is a specification.

My'invention is an improved attachment for Cultivators, especially adapted for use in connection with sulky-cultivators for uncovering such plants in the rows as become covered by the earth thrown upon them by the plows; and it consists in the peculiar construction and combination of devices hereinafter fully set forth and'claimed.

In the accompanying drawings, Figure 1 is a perspective view of my improved plant-uncovering attachment, showing the same disposed in operative relation to a sulky-cultivator. Fig. 2 is a side elevation of the same. Fig. 3 is a top plan View of the same. Fig. 4 is a transverse sectional View of the same, taken on a plane indicated by the line a a of Fig. 3.

In the embodiment of my invention here shown I employ a frame 1, which is obliquely disposed with relation to the rowof plants on which it operates and is provided at its ends with supporting-arms 2, the front ends of which are provided with bearings 3, whereby the said arms are pivotally connected to the axle spindles of the sulky cultivator, as shown.

In the frame 1, at one side of the obliquelydisposed portion thereof, is disposed a counoer-shaft 4:, which is jonrnaled in suitable bearings 5, with which the said frame is provided. Said counter-shaft has a sprocketwheel 6 at its outer end and a beveled gear- I provide a sprocket- Wheel 7, which is attached to one of the supporting-wheels of the sulky-cultivator and rotates therewith, and the power from said Wheel 7 a is conveyed to the sprocket-wheel 6, and hence to the counter-shaft 4, by anendless sprocket-chain 8, which connects the said.

wheels 6 and 7.

On the front side of the oblique portion of the frame 1 is secured a rake 9, which is vertically adjustable on the said frame 1 and is here shown as provided with clamping-bolts 10, by means of which it may be secured at any desired vertical adjustment. The frame 1 is provided with rearwardly-extending arms 11, which are at right angles to and on the rear side of the oblique portion of said frame 1. In the said arms are bearings for a revoluble plant-lifting and clod-removing element, which is here shown as a shaft 12, having tangential spurs 13, which are disposed spirally thereon. On one end of the shaft 12 is a spu r-gear 14. Above the revoluble plantlifting and clod-rcmoving elemenp is a clearing element, which is here shown as a shaft 15, having its bearings in'the arms 11 and provided with a series of radial curved spirallydisposed clearing-spurs 16,which areintercurrent with the tangential spurs 13 of the revoluble plant-lifting and clod-removingelement. At one end of the shaft 15 isaspur-wheel 17 and abeveled gear 18. The latter engages the gear 7 of the counter-shaft 4, and hencemotion is communicated from said counter-shaft to said revoluble clearing element. An idlergear 19, which is mounted on a suitable stubshaft that projects from one of the arms 11, engages the gears 1% 17, and hence power is also communicated to the revolubleplantlifting and clod-removing element.

It will be understood that owing to the pivotal connection between the arms 20f the frame and the axlespindles of the cultivator :my improved attachment may be lowered to the ground and caused to operate in rear of the cultivating-plows and obliquely across the rows of plants and that my said attachment may be raised from the ground when it is not desired or necessary that the same shall operate.

Inorder to raise and lower the attachment, I provide a lever 20, which is fulcrumed at a suitable point to the sulky-cultivator and is here shown as fulcrumed below the bar a, which supports the drivers seat b. The rear end of the said lever is connected by a rod 21 to the frame 1. Alift-spring 22,"Which is here shown as a coiled retractile spring, has one end connected to the frame 1 and the opposite end connected to a suitable fixed point,

here shown as the fulcrum of the lever 20. This spring is in practice sufficiently powerful to raise the attachment about eight inches from the ground and to normally maintain the same in such elevated position. When a plant becomes covered by the action of the plows, which can be observed by the driver, the latter by operating the lever 20 causes the attachment to descend,and the action of the revoluble plant-lifting and clod-removing element is such as to remove the clods from over the covered plant and to lift the latter, thereby preventing it from being destroyed, as will be readily understood. The rake which is disposed in advance of the plant-lifting and clod-removing element prevents large or coarse trash from coming in contact with the latter, and the revoluble clearing, element, the spurs of which are intercurrent with those of the plant-liftin g and clod-removing element, keeps the latter from becoming clogged by the lighter trash and removes the same therefrom.

I do not desire to limit myself to the precise construction and combination of devices herein shown and described, as it is evident that modifications may be made therein without departing from the spirit of my invention. w

Having thus described my invention, I claim 1. In combination with a cultivator having soil-stirring devices disposed for operation on the sides of a row, a revoluble plantlifting and clod-removing element disposed for operation on the row, substantially as described.

2. The combination with a cultivator havingsoil-stirring devices disposed for operation on the sides of a row, of a revoluble plant-lifting and clod-removiug element in rear thereof and disposed obliquely with relation to the line of draft and over the row, the said revoluble plant-lifting and clod-removing element being provided with spurs, substantially as described.

3. The combination with acultivator having soil-stirring devices disposed for operationon the sides of arow, of arevoluble plantlifting and clod-removing element, disposed for operation in rear thereof and over the row and provided with spirally-disposed spurs, substantially as described.
